Geomorphology and geotourism for a sustainable development of the Daunia Mts, Southern Italy
No full textLandscape preservation strongly depends on exploration and knowledge of its history and evolution. The acquisition and the analysis of geological and geomorphological features are basic and useful tools to identify the touristic potential and the anthropic impact of a territory. This study aims to enhance the knowledge of the natural and cultural heritage of an area of the Daunia Mts between the towns of Alberona and Faeto, SouthernItaly, marked by neglect and abandonment, through the drafting of a geomorphological map and the proposal of geotourist itineraries and routes. The results highlight the potential competitiveness and attractiveness of the study area by contributing to the promotion of a sustainable development of a marginal territory. Such data may encourage a form of fruition that promotes knowledge, appreciation, and environmental awareness, in a fragile territorial context
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
UAV-based high-resolution mapping of a complex landslide: an example from Basilicata, Southern Italy
Full text linkThis paper accompanies a UAV-based geological-geomorphological
map (1:1,000 scale) of a complex landslide periodically re-activated,
localized not far from the town of Potenza in Basilicata, southern Italy.
A fixed-wings eBee drone equipped with a conventional digital RGB
photocamera (senseFly S.O.D.A.) was used to collect airborne digital
elevation models (DEMs), orthophotos, and density point clouds in
2014 and 2018. The two photogrammetric surveys helped us to
quickly detect the features of the new mass movement episodes.
Three Google Earth Pro orthophotos filled the lack of information of
the years in between. Topographic contours of the landslides with
their morphological scarps and geological data from the 2018 field
survey were processed using free and open-source software QGIS
3.22.4. For graphic adjustment and the final layout, the main map
was imported into Adobe Illustrator CC 2018 and CorelDraw and
embedded into an A0 map frame.
The geological-geomorphological map reports a detailed
representation of the bedrock geological structures, the ancient
landslide bodies now stabilized, and the recent landslides occurred
from 2014 to 2018 as deduced by the multitemporal analysis.
Geomorphic features and facies analysis allowed us to interpret as
debris flows and mud flows the depositional processes responsible
for the genesis of the landslide bodies reaching the thalweg of the
Basento River
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
